I need to integrate 4 different types of sensors with different sampling frequencies to Arduino. Is Arduino capable of performing parallel data acquisition in real-time ?
Depends… aquiring Data from much more than just 4 sensors is definetly possible.
And technically it’s also possible to read from those sensors with different frequencies, but i wouldn‘t recommend it… it‘s either very complicated, or could cause a ton of problems.
The best method is to read at your highest frequency and only read the lower frequencies every other time, but that‘s also pretty problematic…
Here‘s a link to a better explanation of how that could be done (and how problematic it would be) :
